Electrical Impact of Photovoltaic Plant in Distributed Network [PDF]

2007 IEEE Industry Applications Annual Meeting, 2007
This paper presents the problem of power penetration of photovoltaic (PV) systems in urban networks. After a qualitative problem description, two different environments for PV systems have been analyzed: rural and urban networks. Concerning the rural network, a single line has been simulated in order to evaluate the relation between the number of PV ...
